i thought he had done a dance move apparently not lol....

also joe on xtra factor of what the contestnats did that week was hilarious

I think it was part of the act to as 3 seconds later the male dancers do the same,I've watched it a few times on youtube and I'm convinced it was meant to happen

Yes,,i thought was part of his move too..but that floor did look slippy and shiny..

Yeah I thought it was one of his new dance moves: "The Stumbling Man"
Especially since the backing dancers copied him three seconds later

Joe was hilarious on Xtra Factor, when he fell over and you could just hear him laughing, made me laugh with him
That security guard seems cool as well, when he whispered to Olly that he'd miss him the most
Did anyone hear Joe swear when he fell off his chair?

Olly did genuinely slip.
